Hi,
I am having the same problem here. I run the command "echo $PATH" and this is the output:
/apps/rdp_classifier/2.13:/apps/ea-utils/211021/bin:/apps/ea-utils/211021/:/apps/muscle/5.0.1428/bin:/apps/bwa/0.7.17/bin:/apps/raxml/8.2.12/bin:/apps/vsearch/2.21.1/bin:/apps/mothur/1.45.3/bin:/apps/openmpi/4.1.1-ofed51/bin:/apps/ghc/9.0.1/bin:/apps/amazon-corretto/17.0.2.8.1/bin:/apps/R/4.0.5/bin:/apps/singularity/3.7.3/bin:/apps/qiime/2021.4/blast/bin:/apps/qiime/2021.4/bin:/apps/gcc/10.3.0/bin:/cm/shared/apps/slurm/current/bin:/apps/scutils/bin:/cm/local/apps/environment-modules/4.5.3//bin:/usr/local/bin:/usr/bin:/bin:/usr/lib/mit/bin:/sbin:/usr/sbin:/cm/local/apps/environment-modules/4.5.3/bin
